Inside the gearbox is a pipe system 3 to supply moving parts of the transmission, such as bearings and gear teeth arranged. The pipe system 3 is part of a lubricant circulation system, wherein preferably oil is used as a lubricant.

To supply gear parts, pipes end in spray devices 5 having nozzles for injecting the lubricant in the engagement region of the Verzahnteile. These nozzles are as seitli che holes formed in the respective pipe end, from each of which an oil jet 8th is sprayed on a Verzahnteil.

To supply bearings, tubes end in bores in the wall of the gear housing 1 wherein each such bore directly via a bore extending radially to the shaft in the bearing shell or via a groove system in the cover of the respective bearing bore 2 provide the bearing in question with lubricant.

Every pipe of the pipe system 3 thus supplies a single service area, which may be a partial area of a toothing, in particular an engagement area of a toothing, or an area of a bearing.

The pipe system 3 is to a distributor 4 connected, which is supplied via a shaft pump, not shown, with oil. The shaft pump is designed as a shaft end pump, mounted on a shaft and driven by this. The shaft end pump supplies the distributor 4 via a pressure connection 6 to which she is flanged.

The shaft end pump is as in the pending application DE 10 2007 004 964.3 described trained. All features described therein are part of a transmission described here, preferably in accordance with the claims there. In particular, the connection openings and the fastening means of the pump according to the application are designed so symmetrical that a two-sided mounting is possible. The lower housing shell 9 and the upper shell 10 are also formed according to the application so symmetrical that a two-sided mounting of the pump and a rotational direction invariant operation is possible.

On the lower housing shell 9 becomes an upper housing shell 10 put on to form the gear housing 1 ,

2 shows a detailed view of the transmission housing 1 with the distributor 4 ,

A chamber floor 20 and a chamber wall 21 form a recess in the housing wall of the transmission housing 21 , This recess can be closed by a lid, not shown, in a lid receptacle 27 is used and by means of screws in blind holes 26 is held. One in a sealing insert 28 inserted annular-oval seal closes the recess to the outside to form a chamber. The housing wall thus comprises a plurality of housing parts: a part of the lower housing shell, at least one housing wall and a cover.

In the chamber floor 20 are four outlet holes 24 brought in. In these outlet holes 24 is in each case a pipe end of the pipe system 3 out 1 and 5 inserted and firmly attached. For frictional attachment of each inserted pipe end is rolled, so expanded from the inside. This expansion causes a deformation of pipe end and bore wall, and it is achieved a stable frictional, almost cohesive connection.

In the chamber floor 20 is still a first hole 22 introduced, in which a pressure relief valve, not shown, is arranged. The pressure relief valve relieves the outlet holes 24 . 25 and thus the pipe system. It opens inwards and, if necessary, transfers excess oil to the oil sump in the lower housing shell 9 back.

In the chamber floor 20 is still a first hole 22 introduced, in which a pressure tube, not shown, is arranged, via which the chamber is supplied with oil. This pressure tube is connected as a connecting tube with another chamber or directly to the pressure port of a Wellenendpumpe.

Further outlet bores 25 are provided in the chamber floor in the event that the outlet holes 24 insufficient or in the event that the pipe system of the pipe system 3 out 1 and 5 this requires. For example, these outlet holes 25 have the same diameter as the outlet holes 24 and thus represent holes of the first type.

The first hole 22 and the second hole 23 also have a same diameter, which is larger than that of the holes of the first type. The first hole 22 and the second hole 23 thus represent holes of the second type.

3 shows a section through the transmission housing 1 out 1 ,

In the first hole 22 in the chamber floor 20 of the distributor 4 is a pressure relief valve 30 used, which relieves the chamber towards the gearbox inside.

In the second hole 23 is a connecting pipe 35 inserted at its other end on the opposite wall into a bore of a second chamber 31 is used. This connecting pipe 35 is from the outside into the second hole 23 inserted and pushed through to the opposite hole. Subsequently, both pipe ends of the connecting pipe are rolled into their respective bore, ie widened by plastic deformation with a device inserted into the pipe from the outside in such a way that a press-fit fit is achieved.

The second chamber 31 is as illustrated in mirror image to the distributor 4 formed. She is with a lid 32 covered by screws 33 is attached and how the distributor 4 a sealing insert with seal. The second chamber 31 thus forms a second distributor.

The connecting pipe 35 is rolled at both ends into the holes and thus becomes in a mounting area 36 and in a similar mounting area in the second bore 25 held and fixed. The attachment region preferably extends over the entire length of the bore.

In an additional hole 44 leading to the holes 24 is identical, is a tube 38 to supply a bevel gear shaft bearing inserted and rolled up. The leadership of this tube 38 from the remaining holes from the second chamber 31 would go through the pressure tube 34 and the connecting pipe 35 with special needs.

Through this connection of the pipe system 3 a tree-like topology is formed having two connection nodes, from which the individual tubes run without further branching to the supply areas.

Alternatively, if, for example, the outlet holes 24 . 25 of the distributor 4 not for the pipe system 3 be needed or for reasons of space are not used, so is the pressure relief valve 30 also in the hole 43 used. Thus, only one chamber, the second chamber 31 , involved in the lubricant circulation, while the distributor 4 remains unused. It is thereby a pipe system 3 formed with a star-shaped topology having a branching node, from which the individual tubes run without further branching to the supply areas.

In the distributor 4 becomes in the pictured pipe system 3 to 3 the hole 25 not required. It is therefore closed by a rolled-pipe section, the at its pointing into the transmission interior dead end 37 squeezed and thus closed. As a result, a closure of unneeded openings of the chambers is easy, especially without screwing causes.

For example, the pipe supplies 53 the toothing of the bevel gear 55 and thus the first gear stage. The closed tube at one end 53 has holes through the oil jets 8th leak out the teeth of the bevel gear 55 wet.

For example, the pipe supplies 54 also over oil jets 8th the bevel gear 55 , Thus, a direction-independent supply of the meshing of bevel gear 55 with ring gear 56 provided by spray from two sides.

For example, the pipe supplies 57 via a hole in the housing wall and the cover of the bearing 58 the warehouse 58 , Likewise supplies the pipe 59 the warehouse 60 , The pipes 57 . 59 are the type of supply connection 62 inserted in the corresponding holes and rolled up as described above.

The lids of the bearings are provided on their respective inner side with a groove system for guiding the oil into the space of the bearings. The lids are in total as in the pending application DE 10 2007 017 874.5 described executed. All features described there, in particular according to the claims there, are included in this description. In particular, bearing caps are provided which have branching grooves and thus supply several bearings. In particular, in alternative embodiments, multi-stage gearboxes are provided with separate bearing caps, wherein these bearing caps can each be used in different variants.

The chamber of the distributor 4 is via a connecting pipe 35 supplied from a second chamber, to which also in a branching area 51 Pipes of the pipe system 3 are connected.

To the second chamber is still a pipe 38 connected on its other side into a parallel to the shaft of the bevel gear 55 running bore is inserted and secured by rolling, and in an oil outlet 64 empties. The oil outlet 64 is in turn connected to a groove such that when inserted Kegelradtopf, so completed flange 69 , the bearing of the bevel gear shaft can be supplied with oil.
